<textarea id="text" wrap="on">
Alice was beginning to get very tired of sitting by her sister on the bank, 
and of having nothing to do: once or twice she had peeped into the book 
her sister was reading, but it had no pictures or conversations in it, 
`and what is the use of a book,' thought Alice `without pictures or 
conversation?'

So she was considering in her own mind (as well as she could, for the 
hot day made her feel very sleepy and stupid), whether the pleasure of 
making a daisy-chain would be worth the trouble of getting up and 
picking the daisies, when suddenly a White Rabbit with pink In another 
moment down went Alice after it, never once considering how in the world
she was to get out again. 

The rabbit-hole went straight on like a tunnel for some way, and then 
dipped suddenly down, so suddenly that Alice had not a moment to think 
about stopping herself before she found herself falling down a very deep
well.

Either the well was very deep, or she fell very slowly, for she had 
plenty of time as she went down to look about her and to wonder what was
 going to happen next. First, she tried to look down and make out what 
she was coming to, but it was too dark to see anything; then she looked 
at the sides of the well, and noticed that they were filled with 
cupboards and book-shelves; here and there she saw maps and pictures 
hung upon pegs. She took down a jar from one of the shelves as she 
passed; it was labelled `ORANGE MARMALADE', but to her great 
disappointment it was empty: she did not like to drop the jar for fear 
of killing somebody, so managed to put it into one of the cupboards as 
she fell past it.
